The frontier models score better on GPQA than most human PhD in their specific field of expertise. If you walk in to you local University Department(Assuming you don't live in Cambridge, Palo Alto or a few other places) GPT o3 is going to know more about Chemistry, Biology, Physics, etc than basically all the Grad Students there. If you cant turn that model into a useful tutor then thats 100% a skill issue on your part.
